Abstract
The invention relates to a functional protective material, in particular having a protective function with respect to chemical poisons and/or biological toxins and/or chemical and/or biological hazardous materials, such as warfare agents, wherein the functional protective material has a multi-layer structure that comprises a planar, in particular textile, substrate material and a membrane that is associated with the substrate material, in particular connected to the substrate material, wherein the membrane in itself is permeable to air and water vapor and therefore is provided with a plurality of micropores preferably distributed substantially evenly over the membrane surface. According to the invention, an operating parameter of the membrane can be changed in such a way that the membrane assumes two different operating states, wherein in the first operating state the micropores of the membrane are open and in the second operating state, the micropores of the membrane are at least predominantly closed.
